The tyre pressure values stored at the last
restart will continue to be monitored. Tyre pressure monitor*
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct wheel electronics units are
fitted to all wheels. G
Risk of accident
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign body. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Do not
make any sudden steering movements when
doing so.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

i
The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. The tyre pressure values indica-
ted by a pressure gauge when the vehicle
is at high altitude are higher than those
shown by the on-board computer. In this
case, do not reduce the tyre pressures.
i After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the dis-
play message Tyre Pressure Monitor
Active is shown instead of the tyre pres-
sure display. The tyre pressures are already
being monitored.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the speci-
fied values for monitoring.
In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
i You will find the menu overview on
(Y page 214).
If you wish to define the new reference values
manually:
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions. Also observe the notes in the section on
tyre pressures (Y
page 298).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button to select the
Service menu.
X Press the 9or: button to select

Care and cleaning products
Regular care of your vehicle is a condition for
retaining the quality in the long term.
To care for your vehicle, use the care and
cleaning products recommended and
approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, coarse or rough cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
and do not scour.
Do not touch the surfaces or protective
films with hard objects, e.g. rings or ice
scrapers. You can otherwise scratch or
damage the surfaces or protective films. H
Environmental note
Dispose of empty packaging, cleaning cloths
and polishing wads in an environmentally
responsible manner.
! Do not park the vehicle for a long period
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operating
temperature. Exterior care
Automatic car wash G
Risk of accident
The vehicle is braked when Hold or Distronic
Plus* is activated. Therefore, deactivate Hold
and Distronic Plus before the vehicle is
washed in an automatic car wash.
You can wash the vehicle in an automatic car
wash from the beginning.
! We recommend automatic car washes
with an adjustable 36
high-pressure pre-
cleaning program. In car washes that use
high water pressures, there is a danger that
a small quantity of water may leak into the
vehicle.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! When washing your vehicle in a tow-
through car wash, make sure that the auto-
matic transmission is in position N, other-
wise the vehicle could be damaged.
36 In accordance with the specifications for cabriolet programs. Care

R
Vehicles with a key:
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
R Vehicles with KEYLESS GO*:
Do not open the driver's or front-
passenger door when the engine is
switched off, as this shifts the automatic
transmission to park position Pand locks
the wheels.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain/light sensor may be activated, trig-
gering unintended wiper movements. This
could cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Observe the instructions issued by the
equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle. Do not aim directly at any of the following:
R
tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
Damaged seals or electrical components
can lead to failures or leaks.
Matt finish care* Your vehicle has a clear matt finish. For this
reason, you should make sure that you
adhere to the following instructions to avoid
damage to paintwork due to improper treat-
ment.
! Under no circumstances should you pol-
ish the vehicle. Polishing will make the
paintwork shine.
! When caring for your paintwork, do not
use paint cleaner, grinding or polishing
products, or gloss preservers such as wax.
These products are only suitable for high-
gloss finishes. Using them on a vehicle with
a matt finish results in serious damage to
the surface (gleaming, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
i From the range of available Mercedes-
Benz care products, use only the insect
remover and the car shampoo.
Cleaning the paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-308

Remove the following types of dirt immedi-
ately, whilst avoiding rubbing too hard.
Soak:
R
insect remains with insect remover
R bird droppings with water
and rinse off the treated surface after-
wards.
Remove:
R tree resin, oils, fuels and greases by rub-
bing gently with a cloth soaked in petro-
leum ether or lighter fluid.
R tar stains with tar remover
R wax with silicone remover
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. Otherwise, you could
damage the paintwork.
Cleaning the windows X
Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
product approved and recommended by
Mercedes-Benz.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Under certain circumstances,
deposits such as leaves, petals and pollen
may prevent water from draining away
leading to corrosion damage.
Cleaning the wiper blades G
Risk of injury
Before cleaning the windscreen or wiper
blades, turn the key to position 0in the igni-
tion lock or press the Start/Stop button* until all indicator lamps have gone out in the instru-
ment cluster. The windscreen wipers could
otherwise move and cause injury.
! Only fold the windscreen wipers away
from the windscreen when vertical. Other-
wise, you will damage the bonnet.
! Do not clean the wiper blades too often,
as this will result in damage to the graphite
coating. This could cause wiper noise.
X Fold the wiper arms away from the wind-
screen.
X Clean the wiper blades carefully with a
damp cloth.
X Fold the wiper arms back again before
switching on the ignition.
Cleaning the headlamps X
Clean the plastic lenses of the headlamps
with a wet sponge and windscreen washer
fluid or cleaning cloths.
! Only use washer fluid or cleaning cloths
suitable for plastic lenses. Unsuitable
washer fluid or cleaning cloths could
scratch or damage the plastic lenses of the
headlamps. Care
